HYDROCARBON INCANDESCENT BURNER.

SPECIFICATION forming part Of Letters Patent No. 650,145, dated. May 22, 1900. Application filed February 21, 1900. Serial No. 6,104. (No model.)

To'aLZZ whom it may concern:

Be it known that I, FREDERICK A. CoDY, a citizen of the UnitedStates, residing at Midland, in the county of Midland and State of Michigan, have invented. a new and useful Improvement in Hydrocarbon Incandescent Burners; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to that class of lighting devices which are particularly adapted for lighting streets, buildings, and grounds by burning hydrocarbon; and its object is to convert the hydrocarbon into gas at a high degree of heat and to provide means for cleaning from the conducting-pipe the soot that accumulates in and clogs it.

To this end my invention consists in the construction and combination of parts forming a hydrocarbon incandescent burner, hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure I represents in front view the burner portion of a hydrocarbon incandescent burner according to my invention. Fig. 11 represents the same in transverse vertical section, partly in side elevation. Fig. III represents the same on a much smaller scale, in connection with a supporting-post suitable for street-lighting. Fig. IV represents the hydrocarbon-supply tank as a portion of the street-1am p post. Fig. V represents in vertical section the sprayingchamber on a larger scale.

5 represents a nipple fitted to be engaged at one end with a hydrocarbon-supply pipe and at the other end shaped as a seat for the needle-valve 6, the rod of which extends entirely through the length of the vapor-tube 7 and is provided with a handle 8.

9 is the spraying-chamber, secured to the nipple 5 and tube 7 and communicating with both. The valve 6 is screw-threaded through a partition 10, that crosses the inlet of the spraying-chamber and is provided with a collar 11, which is of a size to fit freely within the tube 7, to be run to and fro through the body to scrape soot therefrom and clean it. The upper end of the tube 7 is bell-mouthed at 12 to direct the scraper 11 into it.

13 represents small perforations through the partition 10 to admit the hydrocarbon.

14 is the sprayer, consisting of abell-shaped coil of wire attached to a screw 15, that closes the hole in the chamber 9, through which the sprayer may be inserted by worming it spirally through the hole. The wire is sufficiently fine and elastic to restore itself to the bell form when fully inserted. The bore of the vaportube 7 is large enough to permit the hydrocarbon gas to pass down it around the stem of the valve 6 to a branch 16, that communicates with the delivery-nozzle 17. V

18 is a needle-valve screw-threaded at 19 into the nozzle 17 and provided with a bandle 20. I

The valves 6 and 1 8 are provided with stuffing-boxes 21 and 22, respectively, to make close joints.

23 is the mixing-chamber, in which air and gas combine and are led to the burner 24.

25 represents the usual mantles, hung upon the arms of a bracket26, that is fitted to slide up and down the body 7 and is provided with a binding-screw 27,by which it may be secured to hold the mantles at the height desired above the burners. The burners and mixing-chamber are also fitted for vertical adjustment on the tube 7 and provided with a binding-screw 28, whereby the position of the mixing-chamber may be at any time adjusted relatively to the gas-delivery nozzle 17, so as to draw in more or less of the surrounding air.

29 is the supply-pipe, connecting the nipple 5 with the tank 30 through'the post 31 and bent pipe-arm 32. The tank is the base of the post and is provided with a closed bottom 33 and top 34. The supply-pipe 29 passes through the top and nearly to the bottom within the tank and is provided with a stop cook 35. e

36 is a nozzle by which a pump may be temporarily connected with the tank to supply it with hydrocarbon 37 and with compressed air, and 38 is a stop-cock for the nozzle.

39 is apipe located within the tank and having its lower end at the proper height for the hydrocarbon to come when first filled, and its mouth 40 is above the tank.

41 is a stop-cock for pipe 39.

42 represents a pressure-gage.

4:3 is a cap to cover the works on top of the tank and is fitted to slide upon the post 31.

44 is a pin that passes through the neck of the cap43 and through the post 31 at one-side of the supply-pipe 29-, and 45 is a padlock to secure the pin in place and prevent unwarranted removal of the cap 43. j

46 is a cup surrounding the vapor-tube 7 and suppliedwith a loose packing 47,015 as-- bestos or other suitable material, to serve as an indestructible wick, to be filled with alcohol, gasolene, or other hydro'carbon to burn as a starter. The burner portion of which this cup is a member being vertically adjustable onthe tube 7, this'cup is provided with an interior side 48 to prevent the starting fluid from running down on the'vapor-tube, so that the starting-cup is annular. I V

Inoperation hydrocarbon is pumped into the tank unti-lit reaches the pipe 39, whose mouth being open the air above the hydrocarbon will force it to rise in the pipe and i flow out of the mouth, thus showing the operatorthat the tank is charged with hydrocarbon. Then the valve 41 is to be closed and the 'pump is used to force air into the tank until the desired pressure-usually from Sixty to eighty poundsis indicated on the gage 42. Nowif the valves 35 and 6 be opened ,linlet-yalveseatin line of the vapor-tube; a

valve to engage the said valve-seat provided with a rod extending longitudinally through the vapor-tube, and a scraper fixed as a collar upon the valve-rod, substantially as described.

3. A pair of lighting-burners a vaporrtube serving as a supply-pipe therefor, a spraying- 5 chamber connected with thesaid vapor-tube; Ij an inlet-valve seat in line of the vapor-tube; a valve to engage the said seat and havinga rod extending longitudinally through the vapor-tube; a scraper-collar upon the said rod and located normally beyond the end of the thus generated is forced by the heatdown the more full and complete when after a minute 1 the pressure 111 the tank Wlll immediately force the hydrocarbon through pipe 29 into the sprayer 14, and in order that thespray may be expanded into gas. the vapor-tube 7 i and the sprayer 14are to be heated by setting fire to the contents of the wick 47. The gas vapor-tube7 to the delivery 17, which may now be opened by turning the valve 20, when the jet of the gas being forced up into the mixing-chamber 23 draws in enough of the surrounding air to form an illuminating-gas of'h-igh candle-power, and that being lighted at the burners 24 heats the mantles 25 to an intense; incandescent glow, which gives ofta greatvolume of diifused white light. This is or so of burning the spraying-chamber 9 becomeshot, the vapor-tube 7 and the sprayer 1 4 usually being red-hot in service. This causes a portion of the hydrocarbon to be cdlr lje charred, forming soot that very soon clogs the tube7. After shutting the stop-cock land unscrewing the stufi'ing-box 2l the vapor-tube 7 may becleaned by drawing the n scraper 1'1 with the valve-rod 6 throughit;

Having thus fully described my invention, what I believe to be new, and desire to secure by Letters Patent, is the following:

1. A pairof lighting-burners; a vapor-tube located between the burners and communicating therewith from below; a spraying- 1 said vapor-tube, and this tube provided with Ea bell-shaped mouth to receive the said collar, substantially as described. y v 4. A pair of lighting-burners having asupply-pipe; a spraying-chamber located over them and'com'municating with the said pipe; and a sprayer of coiled wire adapted to be Y wormed into. the said chamber and provided jwitha screw to close itsentering-hole, substantially as described. V f

5. A vertical vapor-tube serving asa supply-pipe for hydrocarbon-burners; a pair of burners ad justably secured upon the vapor- 4 tube, and an annular starting-cup located between the burners and around the said vapor tube, substantially as described. I

In hydrocarbon-burners, a vapor-tube serving as a supply-pipe to th'eJburneI'S; a gas-delivery nozzle connected with the lower portion of the vapor-tube a'ndpointing in a direction parallel with the va'por-tube; and burners supported by the vapor-tube and having their inlet opposite to'the said nozzle, the said burners beingadjustable along the vapor-tube to and from, the said nozzle, substantially as described. l

In testimony whereof I aflix' my signature in presence of two witnesses. FREDERICK A. CODY.
